Montreal Cognitive Assessment Arabic version: reliability and validity prevalence of mild cognitive impairment among elderly attending geriatric clubs in Cairo
Rahman TT, El Gaafary MM.. Geriatrics & gerontology international, 2009-03-01
Topic: Risk, prevention and care in population studies
Aim Mild cognitive impairment (MCI) is a clinical label which includes elderly subjects with memory impairment and with no significant daily functional disability. MCI is an important target for Alzheimer's dementia prevention studies. Data on the prevalence and incidence of MCI varies greatly according to cultural difference. The first aim of this study was to assess the reliability and validity of Montreal Cognitive Assessment (MoCA) Arabic version in MCI detection. The second was to determine the prevalence of MCI among apparently healthy elderly people attending geriatric clubs in Cairo. Methods In stage I reliability & validity of MoCA Arabic version were assessed in reference to Cambridge Cognitive Examination (CAMCOG). In stage II prevalence of MCI was estimated using Arabic MoCA among apparently healthy elderly attending geriatric clubs. These geriatric clubs were randomly selected from different regions in Cairo governorate. Results Test-retest reliability data of the Arabic MoCA were collected approximately 35.0 +/- 17.6 days apart. The mean change in Arabic MoCA scores from the first to second evaluation was 0.9 +/- 2.5 points, and correlation between the two evaluations was high (correlation coefficient = 0.92, P Conclusion Older age, female sex and less education are the independent risk factors for MCI among apparently healthy elderly subjects attending geriatric clubs in Cairo.
Key findings
- Aim Mild cognitive impairment (MCI) is a clinical label which includes elderly subjects with memory impairment and with no significant daily functional disability.
- Results Test-retest reliability data of the Arabic MoCA were collected approximately 35.0 +/- 17.6 days apart.
Why it matters
This study tested an Arabic version of a cognitive screening test and used it to estimate how common mild cognitive impairment is among older people in Cairo. It is about measuring and counting cases, not about treating, curing or preventing Alzheimer's disease.
